" i `I, ALEXANDER Gmnnn'a'of Philadelphia, county of Philadelphia, State of Pennsylvania, have invented adaptedpartlytoan upwardly-inclined recess in the bedsteada'ail, and partly to' a down-wardly-inclined i recess in the post. A

My invention also consists in making the said plateswith ribsand recesses, arranged, in the peculiar man; ner described hereafter, `in respect -to the orifices `for receiving the inclined pin, so that, while the rib'of iQ-one plate will fitthe-recess of the other, both plates .L may be alike, and may be'cast from the same pat.

` 4:Genie/ral Description'.

A represents partof the post, aud i o, 'B part of'therail of a bedstead. Into the end ofthe rail islet, and there secured, a i metal plate, D, having at the rear a projectiona, to permit the` formation fin front of an upwardly-inclined y orifice, l), for the reception ot' one-halt' of the nclmed `pin E. A similar plate, `5D, is let into and secured to "i ,the post a, but in a' positionfthe reverse of the plate D, `so thatits orifice, b', may be inclined downward for receiving the otherhalf of the inclined piu ll.

Theplatc D, .in thefrail, hasin front a rib, r1,`ex

.tending from thenpper edgeof the'said plate to its orifice, jb, and adapted tothe recess c, inr the plate D of the post.' In `like manner the latter plate" has a ribd',` adapted ,to arecess, e', in the plate D.

When the rail, withj` its plate, yis-iittedto Vthe plate ofthe post, `witlithe inclined pin projecting half i my into `each plate, as shown in ig."3,`all,1ateral twisting of the rail is prevented by the ribs of one plate fitting into the recessesof the other,-while the position of the pin E is such that the greater the pressure appliedto the top of the rail, the more seV curelywill the latter be bound to the post.

It will be observed, on reference to gs. 1 and 2, that` the plates D and D are' precisely alike, and may be cast from the same pattern, all that is necessary in applying them .being to arrange that for the rail in a positionthe reverse of that for the post, as shown.. In fig. 5 the plates are shown as reduced in size and slightly modified in form, and an advantageous method of securing the plates to the post and rail, by

`means of screws :c x, is'also represented.

Another inodilieation of th'e invention is shown iu fig. 6, the plates in this case taking the form of tubes, which are inserted, in an inclined position, into the post and rail, the outer' end of each plate being cut away so as to form a rib and recess, adapted to a corresponding rib and recess of the opposite plate. In some'cases, also, where the rail and post are'of hard v wood, the metal plates may be altogether dispensed Figures 1 and 2 representthe perspective views of with, and a loose inclined metal pin be adapted, partly to the post and partly to the rail, as shown in `fig. 7. The steadying-lugs y y, illustrated in connection vwith the independent pinin fig. 7,l may be either used lthe partsof the bedstead,t`l 1e latter being thereby rendered unserviceable. It Vwill be.4 apparent that my improvennent obvates this diiiculty, as the pins are removed when the bedstead is taken apart.

` Claims.

arranged, in `respect to the oritices, for receiving thev inclined detachable pin, as set forth.

-In testimony whereof I have signed `my name to this specification in the presence of two subscribing witnesses.
